Installer does not work

[hushicho]

First of all, double-clicking the install.bat file to run it just makes it pop up and then immediately close the first time it hits an error.

Second, I can't export a debug report for you because export_debug just tells you to run install.bat, which doesn't work.

It doesn't explain what its problem is with Python, but it seems to be having a problem with Python. However, the problem isn't with my system, because I've set the required Python version with pyenv and created the venv correctly, and it's worked with literally everything else that uses machine learning.

If I try to install it manually, it inevitably hits this error:

ERROR: Could not find a version that satisfies the requirement torch==2.8.0+cu128 (from versions: 2.9.0, 2.9.0+cu128, 2.9.1, 2.9.1+cu128)

ERROR: No matching distribution found for torch==2.8.0+cu128

Again, this is the only app that has hit this stumbling block. Does this need a very specific version of Python installed? Because the version I have currently set as the local version that established the venv is 3.11.9, which should be firmly within the required range. I'm working on Win11.

I'll appreciate any help you can give.

In case anyone else hits this error, after doing a lot of research, I determined that the CUDA 12.8 Toolkit is essential for this to function basically at all. Kohya's install tutorial mentioned and linked it, so here's the link also used by Kohya, another training app:

CUDA 12.8 Toolkit

It might be good to mention in the install instructions, because without this, you won't be able to install OneTrainer.
